To a/ZZ, whom t may concern:

Be it known that l, CARL STEINHAUSER, a citizen of the United States, residing at Willinsburg, in the county of Allegheny, State of Pennsylvania, have invented certain new and useful Improvements in Water-Indicators; and l do hereby declare thisJ following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art toA which it appertains to make and use the same. Thisinvention relates to indicators, and more particularly to waterindicators and steam-boilers, and has for its object to provide an indicator designed to eliminate 'fragile portions, such as the glass tube of watergage's, and to 'correctly indicate the amount ofwater in the boiler. I

@ther objects and advantages will, be ap parent from the following description.

ln the drawings forming a portion of this specification, and inwhich like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation of the present indicator complete. Fig. 2is a vertical section of Fig. 1 and a portion of a-boiler to which the indicator is connected. Fig. 3 is a transverse sectionon line 3 3 of Fig. 41, showing the gears 'and turbine in top plan. Fig. 4 is an enlarged detail of the indicator and a portion of the slide; and Fig. 5 is a detail, partly in section, showing the connection Fi. 6 is a detail sectional view of one of the radial arms and an adjacent portion of the casting taken on line a: a: of Fig. 3.

Referring nowto the drawin s, there is shown a boiler 5, to which there 1s secured aplate 8, having outwardly-extending upper and lower pipes 9 and 10, respectively,con

'nected therewith.- The pipes have vertically-extending enlarged heads 9 and 10, respectively, at their outer ends and at their inner ends communicate with upper and lower openings 6 and 7 ,formed through the late. p -The opening 6 communicates with the interior of the boiler below the normal' waterlevel thereof, while a pipe 11 ycommunicates with the o ening 7 and extends upwardly within the boiler to a point adjacent to the top thereof andinto the steam-space.

Vertical passages 9a and 10a `are -formed through the heads 9 and 10', respectively,

and the latter is threaded at its outer end for v the reception of a cock 12, provided tofper- A casting 16 is provided with a vdepending i flange 17, which surrounds the upper portion of the head 10 and which is held thereupon by suitable fastening devices 18. The casting extends horizontally and has a vertical passage 19 formed therethrough in which the slide 13 moves; and in its upper face the casting has a circular recess 20 surroundingthe slide and lying concentric therewith.

Gpenings X` are formed in each of the heads 9 and 10 and communicate with thepassages 9a; and 10a thereof, and vthrough these openings X the mercury may be introduced into the grooves 14,- as will beunderstood. After the introduction of the mercury the openings X are filled by plugs X', as shown.

lnwardlyeextending radialarms 21 are secured to the casting outwardly of its recess and at their inner ends have engaged therein vertical screws 22, provided with conical lower ends/23, similar screws 24 being engaged in the casting beneath thescrews 22, the screws of the two series registering in pairs for engagement of their conical e'nds in similarly-formed recesses 25k in the trunnions 26 of horizontal 'pinions 27, which mesh with longitudinal gear-teeth formed, as shown at 28, by grooving the slide. The slide is thus arranged for rotation with the pinions 27, and the` grooves are of such a length that the teeth'of the pinions coming into engagement with the ends thereof limitv the sliding movement of the slide and prevent disengagement of the ends of the slide `from the passages 9a andl 10a.

A circular baljl-raceway29 is formed upon the bottom of the `recess 20, its groove 29" registeringwith a groove 30, formed in an annular plate 31, engaged in the upper portion ofthe recess 20 and having threads at its outer periphery shown at 32 as meshing with threads formed within the recess at the upper portion thereof.

An internallygeared member 38 .is dislio ` slide 12 in the passa es.

posed between the plate A31 and the-raceway 29, extending horizontally, and surrounding the pinions 27 and the teeth 33 of rthis gear mesh with the pinions for rotationthereof. In its upper and lower surfaces the gear 33 has grooves 35 and 36, respectively, which register with the grooves 30 and 29 for the reception of balls 37.,

A steam-turbinev 38 is connected with the gear' 33 for rotation thereof and is connected with the ipe 10, as shown at 39, for the reception o steam therefrom. ,The slide 13 is thus constantly revolved to maintain the surface of this slide in a loose relation to the in-v ner surfaces of the passages 9 and 16, and thus facilitate longitudinal movement of the It will thus be seen 'thatthe slide 13 wil receive thereuponthe weight of a column of water extending to the the water-level within the boiler, thev steampressure on both ends of `the`slide being the same.

lA centrallyivoted bar 40 has one 'of its ends connecte with the slide for movement therewith vertically; but to permit of rotation oi the slide with res ect to the bar, and at its opposite end the ar has a weight 41 of a y weight to exactly balance the slide. An indicator-hand e2 is arranged for movement over a scale 43 and is connected with the bar 4) for movement over the scale when the bar is moved.

' It will be seen that when the water is l` above the level of the opening 6 the upper endl ofthe slide 13 will be subjected to a pressure equal tothe weight ofthe water plus theA steam-pressure within the boiler, While the lower end of theslide will be sub- `iected to the steam-pressure only. By reason of the vturbine and its connection with the slide thelatter is kept in constant motion,y so that stopping of the slide in its sockets will be prevented, and by reason of the pressure of the water up on the slide under the above-recited conditions this slide will be de ressed. As the water level falls the slide wi l rise by reason of constant reduction of weight of water upon its upper end, and, as will be readily understood, this movement of `the. slide will cause the hand 42 to move over n inV the sockets for #vertical and rotary movement, means-for rotating the slide, an Vindicator connected With the slide for movement when the slide is moved vertically, and a balance for the slide.V

2, An instrument ofthe class describedv comprising upper and' lower members having registerin sockets in their mutually-adj acent faces, sai members having passages commu-` nicating with the sockets at .the outer ends thereof, a' slide engaged in thesockets for ven.y tical and notary movement therewithin, said` slide having gear-teeth thereupon, pinions meshing with the gear-teeth, an internal gear surrounding the pmion's and meshing there-4 with,ineans' for supporting the pinions and internal gear, means fordriving the internal gear to rotate the pinions and slide, an indicator connected with the slide for movement when' the slide is moved vertically, and a iiuid conductor communicating with the socket of the lower member and extending above the upper member.'

3. .The combination with a boiler, o'f upper and lower socketed members connected therewith for the reception of water and steam respectively from the boiler into their sockets, said sockets opening through the mutually-adjacent faces of the-members, a slide eng-aged in the sockets for vertical and rotary motion therewithin, a balance for the slide', means for revolving the slide, sealing v material surrounding the slide Within the sockets, and an indicator connected with the slide for movement when the slide is moved vertically.

4. In an indicator, the combination with members, of aslide mounted in the members for sliding and rotary motion with respect thereto, an indicator connected with the slide for movement when the slide is moved longitudinally, said slide having spaced longitudinal grooves therein forming teeth, pinions meshing with the teeth, and means for revolving the pinions to rotate the slide, said pinions being arranged for /engagement of their teeth with the ends of the grooves to limit the sliding movement of the slide.

In testimony whereof I affix my signature in presence of two witnesses,

. CARL STEINHAUSER.
